A CONTINUATION STUDY OF USOE PROJECT NUMBER 1493 EXTENDED THE EXAMINATION OF PROBLEMS IN USING MULTIVARIATE SCALING TECHNIQUES FOR THE MEASUREMENT OF INTERESTS. AN EXPERIMENTAL INSTRUMENT, SIMILAR IN FORMAT TO THE SOCIAL RELATIONS SCALE CONSTRUCTED BY GARDNER AND THOMPSON (1956), WAS PREVIOUSLY DEVELOPED. SUBTESTS ON THIS INSTRUMENT (THE INTEREST ASSESSMENT SCALES) WERE REVISED AND GROUPED INTO EIGHT SUBTESTS--(1) ADVENTURE, (2) ORDER, (3) INFLUENCING OTHERS, (4) NURTURANCE, (5) CONCRETE MEANS, (6) WRITTEN EXPRESSION, (7) ABSTRACT IDEAS, AND (8) AESTHETIC. THE REVISED INSTRUMENT WAS ADMINISTERED TO ALMOST 900 HIGH SCHOOL AND UNIVERSITY SUBJECTS IN SMALL GROUPS. IT WAS FOUND THAT THE INTEREST ASSESSMENT SCALES HAVE POTENTIAL USEFULNESS OVER A WIDE AGE RANGE FROM TENTH GRADE THROUGH ADULTHOOD. (JM)
